I was getting off exit 6, going west on 101, around 9:15 at night, and noticed a bright stationary light in the sky. As I pulled to a stop at the end of the exit ramp, I noticed that it was moving very slowly. I stayed at the stop sign and watched as it went behind the tree line and emerged again. At this point I couldn't make out any shape. A car pulled up behind me so I had to take a right onto Depot Rd. I drove slowly and looked out my window as I drove past a clearing in the trees. I noticed two bright headlights at the front of the UFO, and a dimmer red light to the back left of the headlights. I slowed almost to a stop as it fly by overhead. I stuck my head outside the window looking up, and noticed the outline of the craft- a diamond shape, with no visible wings, two headlights at the front tip, and dimmer red lights around the back end. I heard no sound of an engine, and it continued to move very slowly in the sky. I continued down the road and eventually lost sight of it. I've never seen anything like it.
